The Washington Post’s Capital Weather Gang reports that deteriorating air quality across the Great Lakes, Ohio Valley, Mid-Atlantic, and Northeast could be “as bad as or worse than during the historic 2023 wildfire event.”
“It could get worse before it gets better,” Capital Weather warned.
VERY UNHEALTHY: DC among cities with worst air on earth this morning. 😖
Air quality as bad or worse than during historic 2023 wildfire event. Could get worse before it gets better.

Spending a full day outdoors in Washington, D.C., or New York City is equivalent to smoking roughly 10 cigarettes, according to health experts.
The economic toll is already mounting. For example, Six Flags Great America in Illinois closed on Friday because of “hazardous” air quality.
NEW: Six Flags Great America is CLOSED today, Friday July 17, according to an update on the park website.
Air conditions are still in the “hazardous” category under EPA limits due to Canadian wildfire smoke in the @SFGreat_America area.

“Canada is burning: 700+ active wildfires, 8.2 million acres already destroyed. Smoke choking North America again. This doesn’t feel like normal wildfire season anymore. It feels like a war on our forests,” Our Country Our Choice wrote on X. Notably, OCOC is run by retired US Army Col. Douglas Macgregor.

Earlier, Sen. Bernie Moreno (R-Ohio) said he will “introduce a bill next week to sanction Canada and the responsible Canadian government officials for this atrocity.”
Ohio Sen. Moreno To Introduce Bill To Sanction Canada Over Wildfire Smoke
Tens of millions of Americans are choking on toxic wildfire smoke drifting south from Canada. Years of inadequate forest management, often justified in the name of climate change, have intensified focus on the country’s liberal government.
Across the Northeast on Friday morning, an eerie haze blanketed major cities. Even a brief step outside exposed people to air so toxic, it was like smoking multiple cigarettes.

“The Canadian parliament & Mark Carney’s decision not to do the most basic forest maintenance out of climate activism stupidity is now threatening hundreds of millions of Americans with carcinogens,” Daily Signal’s Tony Kinnett wrote on X.
On Thursday, Sen. Bernie Moreno (R-Ohio) said he will be “introducing a bill next week to sanction Canada and the responsible Canadian government officials for this atrocity.”

Additionally, four Republican members of the House blasted left-wing Canadian Prime Minister Mark Carney in a letter, criticizing his liberal government for not doing enough in terms of forest prevention management.
“This is the third consecutive year we have had to write to Canadian officials about a crisis that Canada has the tools to prevent and has chosen not to,” wrote Republican Reps. John James (Mich.), Jack Bergman (Mich.), John Moolenaar (Mich.) and Lisa McClain (Mich.).
Time for accountability.
Canada’s Wildfire Management Failures Choke Millions Of Americans With Toxic Smoke
Canada’s wildfire management policies are once again falling short, as toxic smoke plumes blanket much of the northeastern US and drive air pollution to dangerously high levels.
Another wave of dense wildfire smoke is forecast to reach New York and New England on Thursday afternoon and evening before it surges into the Mid-Atlantic on Thursday night.

Air quality readings in cities including Detroit, Milwaukee, and Toledo exceeded 500, well above the 300 threshold considered unsafe. Chicago, Cleveland, Minneapolis, and Toronto also recorded unsafe levels, while conditions in Washington, Philadelphia, and New York deteriorated into unhealthy territory.

WILDFIRE SMOKE has made its way to Chicago this morning.
The air condition is extremely poor, as seen in this shot near Grant Park. You can see how much smoke has made its way down from the Canadian wildfires.

Detroit, Michigan now has the worst air quality of any major city on Earth due to Canadian wildfire smoke.
If exposed to the current air quality in the city for 24 hours, it would be the equivalent to smoking about 21 cigarettes. pic.twitter.com/xijW3eDhf1

At this time of year, smoke from Canadian wildfires usually pours into the US, exposing tens of millions of Americans to dangerous air quality.
The recurring cross-border pollution is Canada’s repeated failure to address wildfire prevention and mitigation adequately.

“Canada continues to fail to manage its forests. Controlled burns, thinning and clearing debris would go a long way toward preventing this from happening every summer,” the conservative environmental nonprofit American Conservation Coalition wrote on X.

It should be investigated whether arson or inadequate forest management has contributed to the wildfire chaos in Canada, which is imposing major health risks on the US. Much of the left-wing media points to climate change, while rarely covering forest management failures.
